I've been trying to get the moveable radiator cover to work for the OK mod with no luck. I have set a plane to cover the full length of the radiator named RADIATOR_CURTAIN as it is in the files. I've then uvw unwrapped it and named the texture the same as the object and removed the alpha layer. The cover shows up but does not move with the inputs, I set the OK to have 100% cover would this possibly affect things?
